Cross-domain image matching, which investigates the problem of searching images across different visual domains such as photo, sketch, or painting, has attracted intensive attention in computer vision due to its widespread application. Unlike intra-domain matching, cross-domain images appear quite different in various characteristics. This leads to the failure of most existing approaches. However,...
Depth information acquisition is one of the key technologies of FTV (Free View Television) system. To obtain accurate depth information, an improved depth estimation method is proposed. For each pixel in the reference view and current view, gradients between current pixel and its eight neighboring pixels as well as the average value of the nine pixels' luminance are computed. To increase depth accuracy...
2D mesh-based motion compensation can effectively eliminate blocking artifacts that are common in block matching. However, the main difficulty of the scheme is nodal trajectory in occlusion regions. Besides, mesh design is also important because it is related to the efficiency of motion compensation. This work firstly presents a more efficient and delicate algorithm to generate content-based Delaunay...
